VENETIAN BLIND.

SPECIFICATION forming part of Letters Patent No. 366,837, dated July 19,1887.

Application filed April 5, 1887.

To aZZ whom it may concern:

Be it known that I, FRANK A. How'soN, a subject ofthe Queen of GreatBritaimresiding at Brooklyn, in the county of Kings and State of NewYork, have invented a new and Improved Venetian Blind, of which thefollowing is a full, clear, and exact description.

This invention relates to the construction of blinds of that classcommonly called Venetian blinds,the object ofthe invent-ion being toprovide a blind which may be rolled together at either the top or thebottom of the window, or which may be slid upward or downward into aproperly-formed recess, the invention consisting in the construction andarrangement of parts, as will be hereinafter fully de scribed andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of a portion of a blind constructed inaccordance with the terms of my invention. Fig. 2 is a cross-sec tionalview taken upon a line corresponding approximately with the line xxofFig. 1, and Fig. 3 is a cross-sectional view taken upon a linecorresponding with the line 1 y of Fig. 1. Fig. at is a side view, on areduced scale, of the blind partially wound upon a roller.

The slats 10, entering into the construction of the blinds illustratedin the drawings above referred to, are formed with curved upper edges,2, and with correspondingly shaped recesses 3 in their lower edges, andnear each end of the slats I form apertures that are adapted to receivemetallic bands 11; or, if preferred, wires could be substituted for thebands. One wall of each lower recess, 3, is cut away or chamfered, asshown at 4, the chamfer extending inward to a point adjacent to thevertical wire or band receiving apertures, so that the strung slatsforming the blind may be rolled upon a roller after the manner of anordinaryshade, which would be impossible if the recess were notchamfered, as

Serial No. 233,729. (No model.)

described. Heretotore the lower edges of the slats have been formed withV or U shaped recesses, which would prevent the blind from being rolled,though it could be curved somewhat to enter curved ways above thewindow; but such a construction I do not claim.

The central portion of each slat is cut away, the lower defining wall ofthe cut so formed extending upward at an angle from the front or outerface of the slat, so that when two slats are strung together upon theirsupporting bands or wires It the lower edge 01' the outer face of eachslat will be in a plane beneath the upper defining edge of the recessformed in the slat-body.

Instead ot'havingasingle recess in each slat, two or more recesses mightbe formed therein, and in this case the uncut portions of theslatsbetween the recesses would be apertured to receive the stringing bandsor wires. in forming these recesses they might be arranged so as toimpart the effect of a paneled blind.

By forming the slats as described I provide for the rolling or slidingof the blinds into properly-arranged housings located at either the topor the bottom of the window in connection with which the blinds arearranged.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- AVenetian blind formed of the slats 10, cutaway on their central upper portions, curved on their upper edges at 2,recessed on their lower edges, as at 3, to receive the curved edges 2 ofthe slat below, and one wall ofeach recess 3 being cut away orchamfered, as atet, to allow the blind to be rolled upon a roller alterthe manner of an ordinary shade, the vertical apertures, and theflexible wires or bands 11, passing through the apertures, substantiallyas set forth.
